STOVE.

SPECIFICATION forming part of Letters Patent No. 697,091, dated April 8,1902.

Application filed June 14, 190].

To aZZ whont it may concern:

Be it known that I, WILLoUeHBY F. KIST- LER, a citizen of the UnitedStates,residin g at Burbank, in the county of WVayne and State of Ohio,have invented a new and useful Improvement in Stoves, of which thefollowing is a specification.

My invention relates to cooking-stoves; and it consists in a stovehaving beneath the top an annular chamber, a passage leading thereto,and a direct flue-opening opposite said passage, whereby a direct orindirect passage of the products may be had and the central portion ofthe stove-top be exposed directly to the combustion-chamber.

It consists, further, in the addition to the above of a baking-chamberso arranged relatively to the stove that the greater part of the heatmay be directed to the stove-top or to said chamber at will.

In the drawings, Figure 1 is a perspective view of the stove. Fig. 2 isa central verti cal section thereof, and Figs. 3 and 4 are detailperspectives.

A is the stove, having the grate F, the firepot G, thecombustion-chamber D, and the top Q. The last-named member has in itscenter an opening covered by a plate P, within which is a removable lid0. Below the top is an annular pan-shaped chamber 0, communicating atopposite sides with the combustionchamber G. This annular chamber formswith the stove-top an indirect flue, the products of combustion enteringthe chamber, where they divide, passing around in each side of thechamber to the opposite part, at which point they preferably join andemerge through a single fiue. Depending from the chamber at the entrancethereto for the products is a guiding-flue J, the length of whichdepends on the height of the combustionchamber, and partly surroundingsaid entrance is a grate K, which serves to retard the flame in order toheat that part of the stovetop which is immediately above the saidentrance. At the point of exit of the products from the annular chamberis a damper L, lo-' cated between the combustion-chamber and theexit-flue. when said damper is open, di-

rect passage of the products is allowed to the exit-flue, while whenthat damper is closed Serial No. 64,609. (No model.)

the gases are compelled to pass around in the annular chamber beforeleaving the stove, thus heating the stove-top more thoroughly than whenthe direct passage is open.

It will be seen from the foregoing and from Fig. 2 that the shape anddisposition of the annular chamber leave a central portion M, which isalways exposed directly to the heat of the combustion-chamber, thisportion being normally covered by the lid 0.

T is an entrance to the combustion-chamber, as shown in Fig. 1.

The products escaping from the stove need not pass directly to thechimney, and I prefer to attach to the exit-flue of the stove a casingB, in which is contained, for example, an oven 0, spaced on four sidesfrom the walls of the casing to allow passage of the products around theoven.

As shown in the drawings, I use a number of dampers U V W, locatedbetween the oven and the casing-wall and in the pipe f, leading to thechimney, to change the course of the products relative to the oven-wallsand to regulate their amount.

The oven is shown as supported on a framework Y and as having shelves ab and the oven-casing as having clean-outopeningsde.

The oven and casing need not be above the stove, as shown, but may belocated in any convenient or desirable position relative theretom Itwill be seen that the arrangement of stove, oven, and dampers allows theheat to be largely confined'to the stove-top for cocking materialthereon or to be sent directly to one side Z of the oven or around theoven when a relatively large amount of heat is needed for the latter.

Air is fed to the stove in various Ways in addition to that passingthrough the grate F. A chamber E,fsurrounding the lower portion of thecombustion-chamber G, has perforations leading to thecombustion-chamber,and air is supplied from without by means of thedamper H. Air may also enter through the dampered grating S to completethe combustion of the gases rising from the combustionchamber, and theplate R, which lies immediately above the passage, may be pulled forwardabout one-sixteenth of an inch. This plate extends to a point beyond thegrate K to furnish an additional supply of air at that point. 7

What I claim is- 1. In a stove, a top, an annular pan-shapedsmoke-chamber immediately below said top, a direct flue-opening in saidchamber pro vided with a damper, an indirect flue-opening in saidchamber opposite the first-named opening, a member J forming a passageto the indirect fine-opening, said chamber form ing with the stove-topan annular flue, and leaving the center of the stove-top exposeddirectly to the heat of combustion.

2. In acombined cooking and baking stove, a top, an annular pan-shapedsmoke-chamber immediately below said top, a direct flueopening in saidchamber provided with a damper, an indirect fiueopening in said chamberopposite the first-named opening, a member J forming a passage to theindirect flue-opening, said chamberforming with the stove-top an annularflue and leaving the center of the stove-top exposed directly to theheat of combustion, a casing connected to the exit-flue of the stove, anoven in said casing, and a smoke-pipe leading from the casing, wherebythe greater part of the heat may be directed to the stove-top forcooking, or to the oven for baking.
